SEPARATOR AND STOP FOR LACllNG-HOOK-SETTI-NG MACHINES.

SPECIFICATION forming part of Letters Patent No. 692,340, dated February4, 1902. Application filed September 19, 1900. Serial` No. 30,523. (Nomodel.)

To tZZ'w/om it may concern.'

Beit known that I, JOHN PIERCEl a citizen of the United States, residingat Milton, in the county of Norfolk and State of Massachusetts, haveinvented new and useful Improvements in Separators and Stops forLacing-I-Iook-Setting Machines, of which the following is aspecification.

This invention relates to that class of machines in which articles suchas lacing-hooks, buttons, rivets, and the like are fed from a hopper toa raceway and are taken from the raceWay one by one after being set orattached to a piece of material. Y

I have illustrated and described myinvention as adapted to a machineforsetting lacing-hooks, and particularly as adapted to a machine forsetting lacing-hooks for which I have obtained Letters Patent oftheUnited States, dated September ll, 1900, No. 657,673. In machines ofthis class it is essential that the lacing-hooks shall, Vfirst, notleave the raceway until after they have been set in the upper of theboot or shoe; second, that the lowermost lacing-hook shall be correctlycentered and held in position above the anvil upon which it is to beset, and, third, that after said lacing-hook is set in the shoe-upperthe end of the raceway shall be free for the removal of said lacing-hooktherefrom, while the next lacing-hook on the raceway descends totheproper position upon the raceway above the anvil and the otherlacing-hooks in said raceway are held back. It is further essential thatthe lacing-hooks shall not be manipulated or handled more than isabsolutely necessary from the time they leave the hopper until they areset in the shoe-upper.

The object of this invention is to provide a combined separator and stoppositively operated which shall fulfil the requirements hereinbeforerecited.

The invention consists in mechanism which separates the lowermost hookin a column of hooks from the main body thereof and also centers saidhook above the anvil ready for the setting operation.

The invention further consists in a separator-slide and a stop-slide incombination with a plunger and raceway and mechanism for imparting asimultaneous reciprocating motion to said slides in opposite directions.

The invention further consists in certain combinations and arrangementsof parts, as set forth in the following specification and particularlypointed out in the claims thereof.

Referring to the drawings, Figure l is a right-hand side elevation of aportion of a lacing-hook machine similar to that shown and described inmy United States Letters Patent No. 657,673 with my improved separatorand stop attached thereto. Fig. 2 is a vertical sectional elevationtaken on line 2 2, Fig. l, looking toward the left in said figure, theplunger and separator and stop with connections being shown inelevation. Fig. 3 is a rear elevation of a portion of the plunger,raceway, separator, and stop, with a number of lacing-studs on saidraceway, the same being shown full size and starting to descend. Fig. 4.is a View similar to Fig. 3, with the parts shown in the relativepositions assumed as the plunger is starting to ascend and the lowermostlacing-hook having been set in the material is being removed by theoperator from the raceway. Fig. 5 is a transverse section on line 5 5,Fig. 4.

Like characters refer to like parts throughout the -several views of thedrawings.

In the drawings, 10 is the base-plate of a machine for settinglacing-hooks similar in construction to that shown in my Letters PatentNo. 657,673. 12 is the frame of the machine fast to said base-plate.

The lacing-hooks are placed in a hopper 30, from the bottom of whichthey are taken by an intermittently rotated picker plate 3l, which isfast to a shaft 32, having a bearing 33 in the hopper 30.

The method of conveying lacing-hooks by a picker-plate such as thatshown from a hopper to a raceway is old and Well known to those skilledin the art.

The picker-plate 3l has six lingers or arms 43. The lacing-hooks aretaken by these arms from the bottom of the hopper, and as thepicker-plate rotates in the direction of the arrow, Fig. l, thelacing-hooks are picked up by said arms and carried from the bottom ofthe hopper, as shown, sliding around the roo The hopper 30 is cubo-ff onits upper side at an angle of thirty d'egrees, so that as thelacing-hooks slide off the arm 43 they will not be interfered with bysaid hopper, but will be perfectly free to slide off of the arm 43 andonto the raceway 44, as hereinbefore described. It will thus be seenthat as the picker-plate 3l rotates in the direction of the arrow, Fig.1, the different blades thereof will emerge from the hopper at theright-hand side thereof, and the lacing-hooks thereon will slide off ofthe back edge 43 of each arm before said arm enters the hopper again,thus leaving the way free for said lacing-hooks to slide olf thepicker-plate and onto the reciprocatory raceway without danger of beingstopped by the Walls of the hopper.

In order to prevent dirt from falling into the hopper, I provide a cover79, hinged at S0 to the hopper 30. The raceway 44 is made of two piecesof flat steel 46 47, the part 47 being fastened to the part 46 by blocks4S. The plate 46 is fastened rigidly to the verticallyreciprocalingplunger 49 by a screw 50, stud 5l, and screw 52. The stud passes throughthe plunger 49 and receives a sliding block 53, said sliding blockentering a slot 54 in a lever 55. Said lever 55 is pivoted to a stud 56,fast to the frame 12, and is rocked upon said stud by a cam fast to themain shaft of the machine.

The plunger 49 slides in bearings 59 59 in the frame 12, motion beingimparted thereto bythe lever 55. The raceway 44 passes downwardlyoutside the bearings 59 59 from the hopper 30 to the lower end of theplunger 49, where it curves under said plunger 49, ending in a shorthorizontal portion 60.

My improved separator and stop consists of two slides 13 and 14,respectively. Said slides are tted to slide in ways 15 16, formed in thevertically-reciprocating plunger 49, the distance between them beingsubstantially equal to the width of the head. of a lacing-hook, eachslide being equidistant from a vertical plane a a, Fig. 5, passingthrough the center of the plunger 49. The slides 13 14 are beveled attheir lower ends in opposite directions and away from the plane a a,forming chisel-shaped points, and the outer facesof said slides form acontinuation of the periphery of the plunger 49. The upper ends of saidslides 13 14 are connected by links 17 and 18, respectively, to a lever19, pivoted at 20, between the points at which the links 17 18 areconnected thereto, to an ear 2]. on the plunger 49. To the left-handend, Fig. 2, of the lever 19 is secured a friction-roll 22,which entersa slot 23 in the bracket 24, fast to the frame 12. lt will be seen thatas the plunger 49 is reciprocated by the level' 55 the lever 19 will betipped upon its pivot., (the roll 22 remaining stationary as to verticalmovement,) and thus the separator-slide 13 and the stop-slide 14 will bealternately raised and lowered, one'of said slides being raised when theother is lowered, and vice versa.

The operation of my improved separator and stop as a whole, inconjunction with the vertically reciprocating plunger and raceway, is asfollows: The lacing-hooks are delivered to the raceway 44 from thepickerplate 3l and slide down said raceway to the position shown in Fig.3, the lowermost hook 25 resting upon the short horizontal portion 60 ofthe raceway 44, with the left side of the head of said hook touching theright side of the stop-slide 14, the weight of the hook 26 and thecolumn of hooks on the raceway pushing the hook 25 into position shownin Figs. 2 and 3 and bringing said hook into a vertical positiondirectly above the center of the anvil 64. The plunger 49 is shownraised in Figs. 2and 3 and just beginning to descend. The operator nextplaces the upper of the shoe in the proper position over the anvil 64,Fig. 2, and the plunger descends. As the plunger descends theseparator-slide 13 moves down toward the horizontal portion 60 of theraceway and the stop-slide 14 moves in the opposite direction withrelation to the raceway until the lowermost ends of said slides areequidistant from said raceway, with the head of the hook 25 held betweensaid ends. The machine is so timed and adjusted that when the shank ofthe hook 25 reaches the surface of the shoe-upper the head thereof isfirmly held between the ends of the separator and stop slides, centeringthe hook above the anvil as the plunger continues its descent andholding the hook firmly in position, so that the shank of said hook maybe forced through the leather of the shoe-upper without the necessity ofpreviously punching a hole in said upper, and then bringing said holeinto alinement With the center of the anvil and of the lacing-hook aboutto be set in said upper. The shank of the lacing-hook 25 is driventhrough the shoe upper 69 and clenched upon the anvil 64. Theseparatorslide 13 then moves down and the stop-slide 14 up, leaving theportion 60 of the raceway 44 free, so that when the plunger 49 rises asuf- IOC IIC

icient distance for` the upper to clear the anol' the lacing-hook 26 thestop-slide 14 will have descended a sulicient distance to prevent saidhook 2G from sliding off the hori- Zontal portion 60 of the raceway 44.

It Will be seen that the lacing-hooks in my improved lmachine are notmanipulated or touched by any moving piece except the race- Way from themoment they leave lthe hopper until they are separated, centered, andheld in position above the anvil by my improved separator and stop.

Having thus described my invention, what I claim, and desire by LettersPatent to secure, is
